I would wait if I were you, why not get a 2011 model for the sake of waiting 3 weeks, I would.
On a side note, I hope that when I can buy my Camaro later in the year, they are dealing on 2010 models to get them off the lot!
I'm not proud, I'd drive a 'new' 2010 model to save a buck or two!
Did that with my wife's MX5 - bought a brand new 2007 model at the beginning of 2008 and saved over $5000 off sticker due to the dealer needing to get it off the lot.
